On my runs water this year bright yellow pineapples and pink plum were the main pop-up baits that produced fish, even though the water is quite murky.
Last year on Nazeing, very clear water, even brown baits were found in water as deep as 15ft by tufties.
Now I've explained that, for years my favourite pop-up colour has been a brown/red colour , even fading to washed out in the garlic spice flavour of my own. It produced as part of a snowman, (over a food source bottom bait) or as an individual on its own in numbers of waters. Possibly because it does work so well, I have complete faith in it almost everywhere; in fact last year it produced most fish on Bromeswell, although this year I did not use them for some strange reason.
